2.1 Safety Precautions

In addition to the precautions listed throughout this manual, you must read and understand the following statements

regarding hazards associated with AC servo development system.

ATTENTION: Some ground potential of the IRMCS2011 system is biased to a negative

DC bus voltage potential and kept high voltage potential while power is on. When measuring

voltage waveform by oscilloscope, the scope ground needs to be isolated. Failure to do so

may result in personal injury or death.

Darkened display LED is not an indication that capacitors have discharged to safe voltage

levels.

!

ATTENTION: The IRMCS2011 system contains high voltage capacitors which take time to

discharge after removal of main supply. Before working on drive system, ensure isolation of

mains supply from line inputs [R, S, T]. Wait three minutes for capacitors to discharge to

safe voltage levels. Failure to do so may result in personal injury or death.

Darkened display LED is not an indication that capacitors have discharged to safe voltage

levels.

!

ATTENTION: Only personnel familiar with the drive and associated machinery should

plan or implement the installation, start-up, and subsequent maintenance of the system.

Failure to comply may result in personal injury and/or equipment damage.

!

ATTENTION: The surface temperatures of the drive may become hot, which may cause

injury.
